问题补充：

In the reading room, we found her at a desk, with her attention on a book.

A. seating; fixing

B. seated; fixed

C. sitting; fixing

D. to sit; fixed

答案：

A. seating; fixing

(答案→)B. seated; fixed

C. sitting; fixing

D. to sit; fixed

解析：考查非谓语动词做宾补。第一空考查find+o+oc，sit与her之间为主动关系，故可以填sitting，同时也可以使用seated，不表被动，而是表状态，表示“就座的”。第二空考查with+o+oc,即with的复合结构，fix与attention之间构成被动关系，故使用过去分词fixed。句意：在阅览室，我们发现她坐在桌子旁，注意力集中在一本书上。
